Volcanic supervisory is one of the most destructive natural events that is potentially capable of changing the climate of the Earth. For a long time, scientists have suggested that such a phenomenon could have fatal effects on the planet. However, a new study of ecologists from the University of Saint-Endrus proves that although cataclysms will be serious after supervisory, they are unlikely to lead to the complete disappearance of humanity.
In order to model the possible consequences of supervisory, researchers have studied ice cores from Greenland and Antarctica, as well as sedimentary rocks from the Pacific. They found traces of ancient eruption-particles of volcanic ash formed during the super-eradge of Los-choyos. This eruption, which happened 79 500 years ago in modern Guatemala, received 8 points according to the volcanic expression index (VEI) - a minimum score for supervisions. The eruption of Los-choyos caused a temporary cooling, which lasted from 10 to 20 years, but the climate completely recovered in about 30 years.
In order to better understand the influence of supervulcans, scientists have compared ancient events with one of the most powerful eruptions of the present - the explosion of Gori Pinatubo (Philippines) in 1991. On June 12, 1991, after several months of seismic activity, the volcano threw 20 million tons of sulfur into the air. This caused a global decrease in temperature by 0.5 ° C for two years (1991-1993). Despite the safety measures that were allowed to save thousands of people, the explosion still caused losses of $ 100 million. Some planes were injured even hundreds of kilometers from the volcano. Scientists say that although supervisions can temporarily cool the climate, they are unlikely to destroy humanity. For example, during the eruption of Los-choyos, modern people already existed, and despite the catastrophe, Homo Sapiens was able to survive. The last known supervisor occurred 25 500 years ago in New Zealand (Oranua). Such events are extremely rare, so the likelihood that modern humanity will witness super -editing is small. "Our results improve the understanding of how persistent the climate can be for sulfate emissions as a result of supervisions," explains Helen Innes, the leader of the study.
Although supervisions can have a serious impact on the climate, they are not the end of the world. Humanity has enough knowledge and technology to minimize risks and adapt to such catastrophes. And although such events are rare, the study of past eruptions helps us to get better for possible challenges in the future.
